Data for "Mueller Matrix Extrapolations from Linear Partial Polarimetry"

, 2022
To demonstrate our method for extrapolating full, depolarizing Mueller matrices from fewer than 16 measurements, we measured an ensemble of roughened plastic bricks using a Mueller imaging polarimeter and a linear Stokes camera. The Mueller matrix images

A method for reducing specular reflections in Mueller matrix imaging

Optics Express
Mueller matrix polarimetry has emerged as a powerful tool for non-destructive optical analysis of biological tissues and bioorganic materials, offering detailed insights into polarization-specific properties such as diattenuation, retardance, and depolarization.

Mueller coherency matrix method for contrast image in tissue polarimetry [PDF]

SPIE Proceedings, 2007
In this work, we propose the use of the Mueller Coherency matrix of biological tissues in order to increase the information from tissue images and so their contrast. This method involves different Mueller Coherency matrix based parameters, like the eigenvalues analysis, the entropy factor calculation, polarization components crosstalks, linear and ...

CHARACTERISTIC FEATURES OF MUELLER MATRIX PATTERNS FOR POLARIZATION SCATTERING MODEL OF BIOLOGICAL TISSUES [PDF]

Journal of Innovative Optical Health Sciences, 2014
We developed a model to describe polarized photon scattering in biological tissues. In this model, tissues are simplified to a mixture of scatterers and surrounding medium. There are two types of scatterers in the model: solid spheres and infinitely long

Multispectral Mueller matrix imaging dark-field microscope for biological sample observation

, 2019
Mueller polarimetric imaging in dark-field observation shows a contrast enhancement between healthy and cancerous human colon tissue in some reports. We have developed a Mueller-matrix microscope system that combines a dark-field polarization illuminator

Mueller matrix imaging for skin cancer detection [PDF]

, 2004
Over one million Americans are afflicted with skin cancer each year. Even though skin cancer has a 95% cure rate, approximately 10,000 people die in the United States each year of this disease.

Customized depolarization spatial patterns with dynamic retardance functions

Scientific Reports, 2021
In this work we demonstrate customized depolarization spatial patterns by imaging a dynamical time-dependent pixelated retarder. A proof-of-concept of the proposed method is presented, where a liquid–crystal spatial light modulator is used as a spatial ...

3D Mueller-matrix-based azimuthal invariant tomography of polycrystalline structure within benign and malignant soft-tissue tumours [PDF]

, 2020
We introduce a method of azimuthally invariant 3D Mueller-matrix (MM) layer-by-layer mapping of the phase and amplitude parameters of anisotropy of the partially depolarizing layers of benign (adenoma) and malignant (carcinoma) prostate tumours.
